I've got to admit I don't think I'm treated any different. I've got this bad habit that when someone mentions my weight loss I DO go into how I've lost it. And of course then I have to go into it further when it's said to be "meat and cheese".
As for how I treat others? I think I'm a little more confident than I used to be, so I'm thinking that's making me more open to others. Well, not THAT open. lol. But it allows me to look UP at people now instead of stare at my feet. I know I'm not beautiful but I'm happy with me and right now that's all (well, that and the fact that my DH seems to be enjoying this new body. lol) that matters.
